The primary effect of the whole engineering is generating electricity that also meets the demand of shipping, drift wood, flood control and etc.This engineering use concrete gravity dam to prevent the water and overflowing dam to sluicing. The design water level is ,its corresponding flow amount is 11000m3/s .The check level is 水利水電工程專(zhuān)業(yè)畢業(yè)設(shè)計(jì) 5 ,its corresponding flow is 14100m3/ regular water retaining level is 284m .The crest elevation of the nonoverfall dam is , the foundation of dam arrives to 192m height,The max height of the dam is ,The upstream dam slope is 1: ,the downstream dam slop is 1: ,the crest elevation is . The elevation of the water intake of the plant is .The width of bottom of the river vale to this hinge is about 80m。 According to disposal, the overflowing lies in the middle of riverbed, whereas factory lies in the middle of overflowing dam .Because the left shore is much flater which can lay the switch station. This engineering uses such disposal that the hydroelectric station is behind the dam. We choose the mixed hydraulic turbine, whose diameter is and is kw electricity. It is ensured to generate 184000 kw electricity. The width of the main power house is 19m,the length is . All kinds of auxiliary equipment and other kinds of rooms assemble in deputy house. This design concludes the penstock embeded in dam.Key Wo
